" INTERNALLY STOPPERE D BOTTLEL SPECIFICATION forming part bf LettersPatent No. 376,916, dated January 24, 1888;

A Application filed July-21,1887. ssnalnmntot (No modelJ 1 I .To allwhom it'may concern.-

-Be it known that I, DANBYLANDs, a subject of the Queen of GreatBritain, residing at Stairfoot, near Barnsley,in the county of York,

England, have invented new and useful Improvements inInternally-Stopp'ered Bottles, of which the following isa specification.

My invention relates to improvements in internally-stoppered bottleswhich have valves in their. necks, by which means the said bot tles canbe opened; and-the objects of my improvements are to improve upon myprevious patents taken out for the said class of bottles.

I attain these objects by constructing and manufacturing the saidbottles in the manner herein described and illustrated in theaccompanying drawings, in which- I Figure 1 is a sectional elevation oftop por:

tion of the mold wherein the bottle isrblown,and'

shows a section of the neck of one form ofimproved bottle blown thereinand connected to.

.an ordinary blow-pipe, P. Fig. 2 is a sectional elevation of improvedbottle-neck,s howing my improved ,valve fitted therein.

The mold and spindle shown in Fig. 1 are not part otthe invention whichIseek to patent by'this present application, but they are the subject ofa pending application, Serial No.

232,298, filed March,24, 1887, in the United States Patent Ofiice. Theyare shown here, however, for thepurpose of explanation and to enablemeto illustrate withunore clearnes's my invention in bottles hereindescribed and claimed.- j

Referringto Fig. 1, the mold M is made in two portions, m m", which arehinged together at the bottom in the ordinary manner. In

I connection with the said mold M is a spindle,

S, a portion, 8, of which is threaded and screws through a boss, I),which can be attached to the part m of mold M, as shown, or attached toany other suitable article. When the mold M is prepared for receivingthe" viscous or molten glass for forming the bottle, the threaded end sof the spindle S projects a suitable distance within the mold M, and on'this projecting portion 8' of the spindleS is placed (in asuitableposition) arin'g of asbestos or other suitable substance, -.R.The viscous or molten glass attached tothe end of the blow-pipeP, andwhich has been worked up on the marver in the mold Min the usualv way,after which the halves mfin? of themold M are closed, and

" then the'bottle is blown up inthe mold M, as

shown. The spindle Sis then causedtorevolve(byany suitable mechanicalmeans) in a direction which unscrews it from the niold M. In so doingit-leaves the ringof asbestos or other substance, R,'within the indentA, which the end of the screwed portion 8 has 7 formed. The bottle isthen taken from the mold Mland handed to the bottle-maker, who formsamouth thereon and punches the hole is through the bottom of the indent Aby means of suitable tools. It is subsequently annealed, after which theringR isremoved from the in 'dent A- By this means a suitable groove orunder-cut, g, is formed within thesaidindent A.

Referring to Fig. 2, the valve V is prefer-' ably made of glass, and hasa square or other head, h, and a stem which has a portion, t, a;

recessed portion, t, and an enlarged portion, t which is-formed withsuitable male threads in the'indent A. This enlarged portionjthasanysuitable number of horizontal slots, m.

Before the valve V is screwed into the indent,

A anindia-rubber or other pliable washer, to, is placed onto therecessed portion 25, and the flexible washer or ball to is also placedat the 7 bottom of the portion t. The valve Vis then washer w ispressedin along with the valve V until it arrives at the groove or under-cut y,when it expands and fits itself into said groove 9. The valve V is thenfitted complete in the indent A, and cannot be' entirely unscrewed ordrawn from said indent A, By giving the.

screwed into the indent A, and the pliable" head h of the valve V anunscrewing twist the ball or washer to is withdrawn or forced by meansof the pressu-reoin the bottle from the hole It. By this means thepressure of gas in the bottle escapes out of said hole It and passesalong the oblong slots m, after which it passesout of the indent A andescapesbetween the head it and the bottle-neck; I

I would haveit well understood that the valve V, hereinbefore'described,is for the, v

. 7s to correspond with the female threads a formed purpose of beingused in combination with internally-stoppered bottles whose stoppers areeither globular or any other shape.

By means of the arrangement herein described and illustratedinternallystoppered bottles can be opened without the aid of an opener,and the internal-stoppers, F, released from'their seatings a without theapplication of any external mechanical force.

To open bottles fitted with valves, as shown at Fig. 2, the said valve Vis turned by the hand in an unscrewing direction. By this means theinternal gas under pressure escapes out of the hole K, when the internalstopper, F, falls, and then the contents can be poured out. When it isrequired to refill the bottles, the valve V must be screwed up so thatthe washer to hermetically seals the hole K.

What I claim as new, and desire to secure by Letters Patent, is a 1. Inconnection with an internally stoppered bottle, the indent A, providedwith a hole, K, eom municatin g with theinterior of the bottle, incombination with valve V, adapted to work in the indent and to close oropen the hole K, so as to allow the gas or air in the bottle to escapethrough the valve at pleasure, the valvebeing secured to the indent bywasher X, resting in a groove, g, in the indent and a recess, t, in thevalve-stem, substantially as shown and described.

2. In connection with an internally-stoppered bottle having an indent,A, provided with a groove, 9,. and hole K, a valve,V, made withportionst t f, with slots M, and a head, 72, for screwing andunscrewing, and having a washer, X, and washer V, substantially as shownand described,

In testimony whereofl have hereunto set my hand and seal in the presenceof two subscribing witnesses.
